I would like to make pulseaudio work on my Raspberry Pi 3 without X installed. I'm using the Arch Linux ARM distribution and these are the packages I have installed related to pulseauio and alsa:
$ pacman -Qsq pulse libao libpulse pulseaudio pulseaudio-alsa pulseaudio-zeroconf $ pacman -Qsq alsa alsa-firmware alsa-lib alsa-plugins alsa-utils pulseaudio-alsa zita-alsa-pcmi
omxplayer installed as well and I can play sound without X very well with
omxplayer -o local sample.mp3. I would like to have pulseaudio running in the background and play sound.
This is what I've done so far:
I launched pulseaudio with
sudo pulseaudio --system -v and in another shell session (with my own user) I tried the following commands and none of them worked:
aplay -D pulse sample.mp3.
ffplay sample.mp3 - Failed saying
$DISPLAY is not set.
The first 2 made the
pulseaudio process print the same messages saying there is a request from a process named
aplay to produce sound but I recieved no.
alsamixer to see if the sink is not muted or something and it is not.
This is the output of
pactl list sinks:

Any idea why I can't get sound? I don't want to use
omxplayer although it works because eventually I want to play sound through the network.
